Since you have bought a OnePlus 3/3T/5/ OnePlus 5T smartphone on Amazon.in in the past, we are excited to announce the OnePlus Referral program on Amazon.in. We are sharing three referral codes below that you can share with your family, friends or anyone else you wish and earn exciting rewards. The person you have referred will have to purchase the OnePlus 6 smartphone from Amazon.in between May 21 to June 15 2018 for a successful referral. With two successful referrals you will earn a OnePlus Bullets (V2) earphone and the person you have referred will get extended warranty for 3 months on their OnePlus 6 smartphone (beyond the standard warranty offered).
